Interface ParameterizedType
- All Superinterfaces:
Type
Collection<String>.
A parameterized type is created the first time it is needed by a
reflective method, as specified in this package. When a
parameterized type p is created, the generic class or interface declaration
that p instantiates is resolved, and all type arguments of p are created
recursively. See TypeVariable for details on the creation process for type
variables. Repeated creation of a parameterized type has no effect.
Instances of classes that implement this interface must implement an equals() method that equates any two instances that share the same generic class or interface declaration and have equal type parameters.

getActualTypeArguments
Type[] getActualTypeArguments()Returns an array ofTypeobjects representing the actual type arguments to this type.Note that in some cases, the returned array be empty. This can occur if this type represents a non-parameterized type nested within a parameterized type.
- Returns:
- an array of
Typeobjects representing the actual type arguments to this type - Throws:
TypeNotPresentException- if any of the actual type arguments refers to a non-existent class or interface declarationMalformedParameterizedTypeException- if any of the actual type parameters refer to a parameterized type that cannot be instantiated for any reason- Since:
- 1.5
-
getRawType
Type getRawType()Returns theTypeobject representing the class or interface that declared this type.- API Note:
- All
ParameterizedTypeobjects from core reflection return aClass. The staticTypereturn type allows other implementations to represent classes and interfaces not in the current runtime. - Returns:
- the
Typeobject representing the class or interface that declared this type - Since:
- 1.5
-
getOwnerType
Type getOwnerType()Returns aTypeobject representing the type that this type is a member of. For example, if this type isO<T>.I<S>, return a representation ofO<T>.If this type is a top-level type,
nullis returned.- Returns:
- a
Typeobject representing the type that this type is a member of. If this type is a top-level type,nullis returned - Throws:
TypeNotPresentException- if the owner type refers to a non-existent class or interface declarationMalformedParameterizedTypeException- if the owner type refers to a parameterized type that cannot be instantiated for any reason- Since:
- 1.5
